Rear Axle Seals
 

Both rear axle seals are leaking on my 122. Replacing the seals are not a problem to do, it's the other parts that need to be replaced while its tore down. I've found all the parts except the axle bushing (part# 381664-R2). It's a bronze bushing & could be the reason for the seals to leak. I was wondering if anyone might have any ideas as to where I could get them or possibly make them?

You could probably have one made......

I'd just upgrade to the axle with the needle bearing. One of the sponsors can hook you up I'm sure. Much better set up, the bearing is.

I do not know if you can just use the bearing instead of the bushing...... someone here will know. I just know that in the next tractor series they went to a bearing. Don't know if the tubes are different. :Huh: Axles are the same.

the bore in the needle bearing housings is larger. you should be able to measure up the bushing and get a replacement from a bearing shop. should be a common size, axles were pretty much the same except for external brake having rotors on them

Don, can you bore the housing?

sure. We bore them to around 1 1/4 to put needle bearings in them for Dart axles

I have seen the needle bearings & it looked like a better setup to me but it didn't show em in the parts blowup & I didn't know if they were the same size as the bushings. It's just my guess but I'd bet those bushings have never been replaced & it's a 1966 model so I'm sure there's some wear. I just didn't want to tear it down & not replace everything that I could.
